Nice one Moley! Bigger than my recent 45 mile 4000ft cycle over to The Tumble and back. I went well until my wheels fell off. I had not paid sufficient attention to hydration and suffered horrible quads cramp 4 miles from home. You've got a nanosecond to twist your foot out of the cleat before your leg goes rigid in mind-buggering pain. If you fail, you risk toppling into a hedge or an artic!
